This Rselenium command works when using Selenium Server 3.4.0 and Gecko Driver v0.18.
remDr$setImplicitWaitTimeout(milliseconds = 15000)
Here's the relevant code block:
remDr <- remoteDriver()
remDr$open(silent = TRUE)
remDr$setImplicitWaitTimeout(milliseconds = 15000)
But when running Selenium Server 3.5.3 with either Gecko v0.18 or v0.19, the same code generates this error:
Selenium message:POST /session/91a1f43f-18b3-4e11-92a9-d738cd4049a4/timeouts/implicit_wait did not match a known command

I've looked for package updates in the Rselenium Github repo and have searched for other info.
Not sure if I'm missing something or should report a bug.
The implementation of implicit wait is now slightly different. Try
remDr <- remoteDriver()
remDr$open()
remDr$setTimeout(type = "implicit", milliseconds = 5000)
You may also wish to set the pageload timeout
remDr$setTimeout(type = "page load", milliseconds = 5000)
The SetTimeouts command maps to the Marionette setTimeouts command, which makes geckodriver compatible with Firefox 56 and greater.
from their release information on github. you should use firefox 56 or greater instead of 55.

I am trying to simply open a browser with RSelenium with the following code:
library(RSelenium)
remDr <- rsDriver(
port = 4446L,
browser = "chrome",
chromever = "87.0.4280.88"
)
remDr$open()
I am receiving the following error:
Selenium message:Timed out waiting for driver server to start.

I have checked and my chrome version is the following: Version 87.0.4280.141. When I run binman::list_versions("chromedriver"), I have the following versions available "87.0.4280.88" "88.0.4324.27". I have tried both of these versions in the script above but I receive the same error. I am not sure what else to try so if anyone has any suggestions, I would greatly appreciate it. I am running this on a Mac.
I am working with a remote server running Ubuntu 19.10. I'd like to initiate a non-headless chrome server and have developed the following script:
require(RSelenium)
eCaps <- list(chromeOptions = list(
args = c('--window-size=1280,800',
"--disable-extensions",
"--use-gl=swiftshader",
"--user-data-dir=/home/user/.config/google-chrome/Profile1",
"--remote-debugging-port=9222")
))
# Google Chrome version is 81.0.4044.138
rD <- rsDriver(browser = "chrome",
chromever = "81.0.4044.138",
extraCapabilities = eCaps,
port =
as.integer(base::sample(seq(32768,65535, by=1),1)))
remDr <- rD[["client"]]
remDr$navigate("https://stackoverflow.com/")
If I log into the box via SSH and start a new R session I can paste the above commands and Chrome server launches with the correct profile and saved passwords required for my purposes.
If, however, I run the exact same commands from RStudio Server this results in an error:
Selenium message:unknown error: Chrome failed to start: exited abnormally.
(chrome not reachable)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

Some thoughts:
I'm only running the selenium server in non-headless mode as I cannot seem to launch Chrome with a saved profile (and saved passwords) when using the --headless argument.
If I use the --headless argument as above then the sever can be sucessfully launched both from within RStudio Server and an R terminal session
It feels like a permissions issue, and I have experimented with changing the RStudio Server user to my same username that I SSH into the box with, as per these instructions. This does not resolve the problem.
version.string R version 3.6.1 (2019-07-05)

Any help appreciated!
I try to connect with Selenium in R using the Chrome browser on Win10.
I installed Chrome 74.0.3729.61 and added the chrome.exe path to the Environment Variables.
devtools::install_github("johndharrison/seleniumPipes")
devtools::install_github("ropensci/Rselenium")
#start selenium
selServ <- selenium()
# check ports
selServ$log()$stderr
# conect using port
sel <- remoteDr(browserName = "chrome", port = 4567)
gives me the following error message:

I found some guidance for Python (Cannot find Chrome binary with Selenium in Python for older versions of Google Chrome) and c# (Selenium WebDriver - Could not find Chrome binary), however, I do not know how to implement it in R.
IMHO you need to download and run chomedriver.exe(if you are using Windows 10, as you mentioned) before to use selenium.
Could you try below solution?
Solution 1. on command window
java -Dwebdriver.chrome.driver="C:/{yourPath}/selenium/chromedriver.exe" -jar "C:/{yourPath}/selenium/selenium-server-standalone-3.141.59.jar" -port 4567
or
Solution 2. direct use R script
rstudioapi::terminalExecute('java -Dwebdriver.chrome.driver="C:/{yourPath}/selenium/chromedriver.exe" -jar "C:/{yourPath}/selenium/selenium-server-standalone-3.141.59.jar" -port 4567')
Yes, both are same command exactly. You are able to use anyone you want.
As the title says, I've got a script written using RSelenium to automate web navigation, using chrome as the browser. This script has worked fine for months now, but today when I tried to run it, I got the following message:
Selenium message:Unable to create new service: ChromeDriverService

I'm pretty sure that I have installed the latest versions of Chrome and ChromeDriver, but this has not changed anything. I'm at a loss as to what caused this error to spontaneously appear today.
If you are using windows, just go inside C:\Users\Jeff\AppData\Local\binman and delete all directories inside (for me 4 directories including seleniumserver and geckodriver). Then just open RStudio and run eg
library(RSelenium)
rD <- rsDriver(browser = "chrome")
remDr <- rD$client
remDr$navigate("https://google.com")
Good luck.
I try to use the RSelenium in windows with IE as browser as it seems there are some discrepancies with other browsers, and need some fixing with the newer versions.
I do as previously instructed in SO answers:
library(RSelenium)
startServer()
remDr <- remoteDriver(browser="internet explorer")
remDr$open()
remDr$open()

Also when starting server or checking for servers I receive errors regarding deprecated use of the function.
For example:
startServer()
Warning message:
startServer is deprecated.
Users in future can find the function in file.path(find.package("RSelenium"), "example/serverUtils").
The sourcing/starting of a Selenium Server is a users responsiblity.
Options include manually starting a server see vignette("RSelenium-basics", package = "RSelenium")
and running a docker container see vignette("RSelenium-docker", package = "RSelenium")
